1T0 all whom it may conccm:

. Be it known that I, WILLIAM K. RHODES, of Portland, in the county of Cumberland and State of Maine, have invented certain new and useful Improvements in Lnbricators; and I do hereby declare thatthe followingisa-full,clear, and exact description of the invention, which e will enable othersslrillcd in the art to which it appertai-ns to makeand use the same, reference being bad to thcaccompanyin'g drawings,

and to letters of reference marked thereon,

which form a part of this specification.

Figure 1 is a side sectionale levation. Fig. 2 is the same with chamber for cooling coms Same letters show like parts.

My invention relates to. lubricating-cups.

It consists, first, ol'a lubricating-cup capable of a vertical motion up and down for the put" pose of opening the cup when it is to be filled and for promoting the discharge of the lubricating compound second, in the combination of the cup with a stand or base.

The invention is intended to be applied to p 25 any part or parts of machines or machinery where it; may be usefully employed, as to journals,jourmi'l-boxes, axles, v8m. a

The cup itself is open at the bottom and :closed solidly at the top. When being filled the cup is turned open end up. It is. then i placed down over a base or stand, which is so made as to exact] y fill and close the opening of the cup. The stand or base has a duct or channel leading from the opening in the hollow of as toconduct the lubricating compound to the point where it is to be applied. The base has an annular chamber to receive a cooling-composition which may act upon the lubricating compound to keep it cool. When the cup is filled with ihlubricatingcompound and placed on its base theair iswhollyornearly exhausted or expelled fromthe cup. The atmospheric pressure is thus suflicient to keep the lubricat, 4S

H 'ed for use-thaws, there wilLbe no dripping or running out of the compound until forced ing compound in itsplacein thecupuntilucedout,asher eihafterdescribed. Thelubricating mechanical methods can be adopted to operate of-the compound remaining-after each instance the inverted clip through a stock or shank, so

, I disclaim any lubricators having cylinders and plungers. .Their operation is difi'ercnt. Thccompound, moreover, oozes up between the plunger-s. and the innerperiphery of the'cylin der, causing fouling and clogging. My invention is exempt from this fault. Further, the cup remains to the degree that it has heen depressed, and iudicatesthe condition or amount.

The method-ofconnection is simply to have a hole to receive the lower end of the stock or shank. In the caseoi journal a. hole in'the journal-box or cap over the journalwouldbe the proper place. 80 I do notclaim the screw-cap, broadly, nor its combination broadlywith the screw-base.

WhatI claim as my invention, and desire to secure by Letters Patent, is-- A lubricating-cup composed of thecombina- 8 .tion of the cup a, basel having chamherg' and duct; 0, and the stock oi-"shankf, as herein set forth. T"

In testimony that I claim the foregoing as my own I aifix my signature in presence of two '90 witnesses. I WILLIAM K. RHODES.
